This series of fixed-voltage integrated-circuitvoltage regulators is designed for a wide range ofapplications. These applications include on-cardregulation for elimination of noise and distributionproblems associated with single-point regulation.In addition, they can be used with power-passelements to make high-current voltage regulators.One of these regulators can deliver up to 100 mAof output current. The internal limiting andthermal-shutdown features of these regulatorsmake them essentially immune to overload. Whenused as a replacement for a zener diode-resistorcombination, an effective improvement in outputimpedance can be obtained, together with lowerbias current.
